This same show is download-able from eMusic.com, and of course, not for free! I don't know anything about how the eMusic version was recorded, but if it was simulcast that's my best guess as to the eMusic source.

The URL is: http://www.emusic.com/album/10813/10813030.html

The eMusic reviewer, Dean Budneck, referred to the band as ""Relix cover boys Umphrey's McGee (Dec/Jan 2005)" and quoted Rolling Stone as saying the band are "leading contenders for Phish's jam-smeared crown."
It's the only live set by Umphrey's McGee eMusic has for download, but they also have the band's 3 studio albums: LOCAL BAND DOES OK, ANCHOR DROPS, and SAFETY IN NUMBERS online for download, as they do for so many releases on The String Cheese Incident's SCI Fidelity Records.
Their reviewer makes note of the band's Progressive Rock precision and high humor, which is a good start on a definition of the 90's and 2000's Jam Band movement.
He refers to "Uncle Wally" and "YYZ" as signature compositions for the band and "Jimmy Stewart" and "Jazz Odyssey" as examples of the band's semi-structured improvisational exercises.
Part of my intention here was to note an online MP3 store source for this very concert, as well as an inexpensive source for the band's 3 studio albums (in fact, eMusic will give anyone who has never tried their service before 50 free MP3 downloads, which is enough to get all the Umphrey's McGee material they have). I am in no way affiliated with eMusic, any other on-line audio file store, or any recorded label and have no vested interested whatsoever in eMusic, SCI Fidelity Records, or Umphrey's McGee. I am only a huge jam band fan and at the moment, retired semi-professional bassist not currently affiliated with any band and never associated with a band that had a "record deal." LOL. :^) I played in dive bars for the most part. I am pointing this out to show I do not benefit from anyone using eMusic, or purchasing anything on SCI Fidelity Records or by the Band Umphrey's McGee and am simply a fan who would appreciate this information if I didn't know it, so I am sharing.

The other part of my intention for this note is to point out an inexpensive source for a good deal of the material available on the String Cheese Incident's SCI Fidelity Records, a catalog seemingly dedicated to the studio albums and a few official live releases of excellent 90's and 2000's Jam Bands. I hope this note is appropriate.

This source doesn't have the skips/flaws that were on the first Matrix source uploaded to the Archive. Great show!
